This idea has been developed and deployed to Canvas
I know that quiz times can be changed/extended by going into each quiz and selecting the student to grant more time ('moderate a quiz'). However, this can prove tedious if you know that one student (or many for that matter), are going to need more time in ALL a course's quizzes than other students. Not just one quiz at a time. A great feature would be to be able to go into a student's settings and extend the quiz times in one fell swoop, if that makes sense. Now, one has to go to each quiz, "moderate it", then select that student and change the quiz time. Repeat for every course quiz.
